XJet

XJet is an Israeli additive manufacturing company based in Rehovot. It develops NanoParticle Jetting, a direct material jetting process for metal and ceramic parts. The site says the process produces dense, complex parts that need little or no machining or post-processing. The company also offers file-to-part software that prepares designs for printing.

Printing technology

• NanoParticle Jetting: inkjet printing with metal and ceramic nanoparticle ink.
• Soluble support: prints support material at the same time as the part.
• High-definition inkjet: printheads with thousands of nozzles give fine control over final part quality.
• File-to-part software: turns designs into production print files.

The site describes the process as powderless and largely automatic, with minimal human intervention and no need for prior or post processing. The site presents the goal as bringing the full material properties of traditional manufacturing to additive parts used in medical and industrial applications.

Materials and markets

XJet lists ceramics such as alumina, zirconia and silicon nitride, metals including stainless steel 316L and 17-4 PH, tungsten carbide cobalt, and precious metals such as sterling silver and 14K and 18K gold. The site names uses in RF antennas, heat exchangers, surgical robot consumables, spinal and dental implants, automotive interior parts, filtration, energy, watch components and premium jewellery.

Precision and applications

The site describes sub-micron precision and says the company holds a patent on its powderless metal and ceramic jetting. Further applications it names include ceramic lattice structures, high-pressure coolers, fluid mixing nozzles, pressure sensors and pharmaceutical laboratory parts. Its parts can include fine details and inner cavities, and can be supplied pre-assembled.
